Caution - Before beginning this procedure, ensure that you are familiar with the cautions and safety instructions described in Safety Information and the information in DIMM Configuration. |
Caution - When a DIMM fails, do not remove the DIMM until a replacement is available. Removing a faulted DIMM and leaving the slot empty might deconfigure the remaining DIMMs. |
See Prevent ESD Damage.
